当局正在审查一段视频显然是其中一名嫌疑人上传到网上的在星期一的致命射击在圣迭戈的伊斯兰中心似乎捕捉到了直播消息人士告诉ABC新闻。
消息人士称，调查人员还在调查此次袭击与虚无主义暴力极端主义的关联程度。
当局表示，三名男子在周一的枪击事件中丧生，其中一名是保安，调查人员表示，他们目前认为这是一起仇恨犯罪事件。
警方称，两名年龄分别为17岁和18岁的嫌疑人被发现死在附近的一辆车里。几名消息人士告诉ABC新闻，当局正在调查两名青少年，凯恩·克拉克和凯勒·瓦兹奎，他们是枪击案的嫌疑袭击者。
有消息称，发布到戈尔网站上的一段视频显示了嫌疑人接近中心然后开火，其中一人被认为是嫌疑人克拉克，他穿着迷彩服，带着车牌。
在…里的后面部分有消息称，在这段视频中，可以看到被认为是克拉克的人把手伸到车的后座，然后开枪打死了瓦兹奎，接着又开了第二枪，结束了自己的生命。
一个Sonnenrad补丁，描绘了一个新纳粹符号，分析人士估计，这可能是一个激进的加速主义组织的补丁据消息来源称，在被认为是克拉克的人所戴的盘子上。此外，枪上的字迹清晰可见，包括不锈钢螺栓的图样和新纳粹徽章，消息来源说。
更多与新纳粹主义和激进加速主义相关的符号在据消息来源称，枪击事件包括一面写有Sonnenrad的旗帜和一个画有党卫军螺栓的煤气罐。
消息人士告诉ABC新闻，调查人员正在检查网上流传的一份冗长的文件，该文件由两篇充满仇恨的文章组成，共75页，据称是由嫌疑枪手撰写的。
据消息人士称，两篇文章都宣扬白人民族主义，表达了对移民、少数民族和其他人的仇恨，以及对喜欢高个子男人的女性的愤怒。消息人士称，瓦兹奎在文章中称自己是一名“加速主义者”，呼应了虚无主义的言论。
不清楚这些文章实际上是什么时候写的——一个旨在确定“目标”的部分是空白的，消息人士说。
消息人士还告诉ABC新闻，据信与克拉克有关的社交媒体账户反映了与虚无主义暴力极端主义意识形态的可能联系。
消息人士告诉ABC新闻，去年年初，加利福尼亚州丘拉维斯塔的警方与瓦兹奎进行了交谈，此前认识他的人表示担心他对极端主义意识形态和大规模伤亡袭击感兴趣，尽管当时的担忧没有达到逮捕的门槛。丘拉维斯塔警察局的一名发言人周二告诉美国广播公司新闻，该部门“向所有受这场悲剧影响的人致以最深切的哀悼”，但拒绝透露回答关于先前联系人的问题。
据负责美国联邦调查局圣地亚哥办事处的特工马克·雷米利说，这两名嫌疑人在网上相遇，并发现他们都住在圣地亚哥地区。Remily在周二的新闻发布会上说，他们似乎在网上变得激进，对各种种族和宗教有“广泛的仇恨”。
“他们不会歧视他们讨厌的人，”Remily说。
雷米里说，调查人员已经发现了概述“他们所设想的世界应该是什么样子的宗教和种族信仰”的文字。他说，当局正在分析这些文字，以了解导致袭击的原因以及如何防止未来的袭击，并调查“激进化是如何发生的”。
当局说，在调查中判断清真寺是否是具体目标还为时过早。
“我们仍在通过电子设备寻找答案，但我可以说的是，他们肯定对许多人有广泛的仇恨，”雷米里说。
当被问及伊斯兰中心的学校是否是预定目标时，圣地亚哥警察局长斯科特·沃尔说，执法部门仍在努力确定“威胁画面”的范围。
瓦尔周二表示，警方正在调查嫌疑人是如何在枪击事件中获得枪支的。他说，这些枪属于其中一名嫌疑人的父母。
雷米利说，在搜查与嫌疑人有关的两处住所时，当局缴获了“大量手枪、步枪、猎枪、弹药、战术装备以及电子产品”。
“到目前为止，在这次调查中，我们已经缴获了30多支枪和一支弩，”他说。
警方说，枪击事件是在周一中午前不久报告的。
根据瓦尔的说法，对视频的回顾显示，嫌疑人与保安发生了“枪战”，保安在清真寺外被杀。
他说，保安人员设法发布了“锁定协议”，伴随着枪声，允许清真寺主要公共区域的人躲藏起来。他说，当时里面大约有140名儿童。
警察局长说，嫌疑人在里面一个房间一个房间地移动，但是没有碰到任何人。他说，在某一点上，他们看着窗外，其中一个人指着窗户，然后从附近的门跑出去，在这一点上，他们“立即与停车场外的另外两个受害者接触”。
被杀害的保安阿明·阿卜杜拉被誉为英雄。
“毫无疑问，他的行为拖延、分散并最终阻止了这两个人进入清真寺的更大区域，那里有多达140名儿童在这些嫌疑人的15英尺内，”瓦尔周二说。
瓦尔说，在枪击事件中丧生的另外两名受害者被当局确认为曼苏尔·卡齐哈和纳迪尔·阿瓦德，他们将嫌疑人的注意力吸引到一个停车场，“不幸的是，他们无法逃离那里”。沃尔说，他们被嫌疑人逼到墙角并被杀害。
警方正在调查潜在的动机，但表示枪击事件目前被视为仇恨犯罪。
沃尔在周一的新闻发布会上说:“这肯定涉及到仇恨言论。”。
消息人士告诉美国广播公司新闻，在两名少年的车上发现了反伊斯兰的文字。
据沃尔说，在清真寺枪击案发生前大约两个小时，圣地亚哥警方接到一个电话，涉及一名17岁的嫌疑人，关于一名离家出走的少年。他说，这名少年的母亲报告说，“她的几件武器”和她的汽车都不见了。瓦尔说，这位母亲还发现了一张纸条，警察局长没有透露纸条的内容。
这位母亲告诉警方，她的儿子和另一个人在一起，他们都“穿着迷彩服”，瓦尔说。
他说，当清真寺的枪击事件被报道时，警察正在试图追踪这辆车，并向一个商场和一所与其中一名青少年有关联的学校派遣了警察。
圣地亚哥伊斯兰中心称它是圣地亚哥县最大的清真寺。
“我们以前从未经历过这样的悲剧，”圣迭戈伊斯兰中心主任、伊玛目塔哈·哈桑在新闻发布会上谈到该中心时说。
哈桑说，他正在发送“祈祷文，声援我们社区的所有家庭，以及我们美丽城市的其他清真寺和所有礼拜场所。”
“把一个礼拜场所作为目标是极其令人愤慨的。我们的伊斯兰中心是一个礼拜场所。人们来到伊斯兰中心祈祷、庆祝、学习，不仅是穆斯林，我们还有各行各业的人，”哈桑补充说。
“不幸的是，我们国家存在的宗教不容忍和仇恨是前所未有的，”哈桑说。
“我们强烈谴责这一骇人听闻的暴力行为，”美国-伊斯兰关系委员会圣地亚哥分会执行主任塔哲恩·尼萨姆在一份声明中说。“我们对受到此次袭击影响的所有人表示同情。任何人都不应该在参加祈祷或在小学学习时担心自己的安全。”
圣地亚哥市长托德·格洛里亚告诉美国广播公司新闻，“我们立即增加了宗教场所周围的巡逻，包括全市的穆斯林、犹太人和其他信仰社区。我想我们会在一段时间内保持这种姿态。”
“我相信，一旦调查结束，那名保安将会被认为拯救了很多很多人的生命，包括很多孩子，他是一个绝对的英雄，不幸地失去了生命，但我们都很感激他，”格洛丽亚说。
“仇恨在圣地亚哥没有家。伊斯兰恐惧症在圣地亚哥没有家，”市长在新闻发布会上说。
San Diego Islamic Center shooting suspect apparently posted video of attack: Sources
Authorities are reviewing a videoapparently posted online by one of the suspectsin Monday'sdeadly shootingat the Islamic Center of San Diego that appears to capturea livestreamof the attack and its aftermath, sources told ABC News.
Investigators are also examining the degree to which the attack could be tied to nihilistic violent extremism, the sources said.
Three men, one of whom was a security guard, were killed in the shooting on Monday, authorities said, with investigators saying they are currently considering the incident as a hate crime.
Two suspects, aged 17 and 18, were found dead in a vehicle nearby, police said. Authorities are investigating two teenagers, Cain Clark and Caleb Vazquez, as the suspected attackers in the shooting, several sources told ABC News.
Sources said a video posted to an online gore site allegedly shows the suspectsapproaching the center and then opening fire,with a person believed to be suspect Clark wearing camouflage fatigues and a plate carrier.
Ina later portion ofthe video, sources said the person believed to be Clark can be seen reaching into the backseat of the vehicle and then shooting Vazquez, before chambering a second round and taking his own life.
A Sonnenrad patch, depicting a neo-Nazi symbol,and what analysts assess is likely a patch for a militant accelerationist group, are both visibleon the plate carrier being worn by the person believed to be Clark, according to sources. Additionally, writings are visible on a gun, including drawings of SS boltsand neo-Nazi insignias, sources said.
Further symbols associated with neo-Nazism and militant accelerationism were found at the scene ofthe shooting, including a flag with a Sonnenrad on it and a gas can with SS bolts drawn on it, according to sources.
Investigators are examining a lengthy document circulating online that is comprised of two hate-filled essays totaling 75 pages allegedly written by the suspected shooters, sources told ABC News.
Both essays promote white nationalism and express a hatred for immigrants, racial minorities and others, as well as anger toward women who prefer taller men, according to sources. Vazquez allegedly writes he is an "accelerationist" in his essay, echoing nihilistic rhetoric, sources said.
It's unclear when the essays were actually written -- a section intended to identify the "targets" is left blank, sources said.
Social media accounts believed to be tied to Clark reflect possible associations with nihilistic violent extremist ideology, sources also told ABC News.
Early last year, police in Chula Vista, California, spoke with Vazquez after someone who knew him expressed concerns that he was interested in extremist ideology and mass-casualty attacks, though the concerns at that point didn't meet the threshold for making an arrest, sources told ABC News. A spokesperson for the Chula Vista Police Department told ABC News on Tuesday that the department "extends its deepest condolences to all those affected by this tragedy" but declined toanswer questions about the prior contact.
The suspects met online and discovered they both lived in the San Diego area, according to Mark Remily, the special agent in charge of the FBI’s San Diego Field Office. They appear to have been radicalized online and had a "broad hatred" toward a wide array of races and religions, Remily said during a press briefing Tuesday.
"They didn't discriminate on who they hated," Remily said.
Investigators have recovered writings that outline "religious and racial beliefs of how the world they envision should look," Remily said. Authorities are in the process of analyzing the writings to learn what led to the attack and how to prevent future ones, as well as looking into "how the radicalization occurred," he said.
It's too early in the investigation to tell if the mosque was the specific target, authorities said.
"We're still looking through electronics to give us the answers, but again, what I can say is they definitely had a broad hatred towards a lot of folks," Remily said.
San Diego Police Chief Scott Wahl said law enforcement is still working to determine the scope of the "threat picture," when asked if the Islamic center's schools were the intended target.
Police are investigating how the suspects obtained firearms in the shooting, Wahl said Tuesday. The guns belonged to the parents of one of the suspects, he said.
During searches of two residences associated with the suspects, authorities seized "numerous pistols, rifles, shotguns, ammunition, tactical gear, as well as electronics," Remily said.
"So far in this investigation, we've seized over 30 guns and a crossbow," he said.
The shooting was reported shortly before noon Monday, police said.
A review of video shows that the suspects got into a "gun battle" with the security guard, who was killed outside the mosque, according to Wahl.
The security guard had managed to put out a "lockdown protocol," which along with the sound of gunfire, allowed those in the main common areas of the mosque to go into hiding, he said. There were some 140 children inside at the time, he said.
The suspects moved room by room once inside, but did not run into anyone, the police chief said. At one point, they are seen looking out a window, with one pointing to the window, before running out a nearby door, at which point they "immediately engage" the two other victims outside in the parking lot, he said.
Amin Abdullah, the security guard killed, has been hailed as a hero.
"His actions, without a doubt, delayed, distracted and ultimately deterred these two individuals from gaining access to the greater areas of the mosque where as many as 140 kids were within 15 feet of these suspects," Wahl said Tuesday.
The two other victims killed in the shooting -- identified by authorities as Mansour Kaziha and Nadir Awad -- "drew the attention" of the suspects into a parking lot "where they were unfortunately unable to flee," Wahl said. They were cornered by the suspects and killed, Wahl said.
Police are investigating a potential motive but said the shooting is currently being considered as a hate crime.
"There was definitely hate rhetoric that was involved," Wahl said during a Monday press briefing.
Anti-Islamic writings were found in the vehicle with the two teens, sources told ABC News.
About two hours before the shooting at the mosque, San Diego police received a call involving the 17-year-old suspect, about a runaway juvenile, according to Wahl. The teen's mother reported that "several of her weapons" and her vehicle were missing, he said. The mother also found a note, Wahl said, the contents of which the police chief did not share.
The mother told police that her son was with another individual and that they were both "dressed in camo," Wahl said.
Officers were attempting to track down the vehicle and dispatched police to a mall and to a school with which one of the teens was associated, when the shooting at the mosque was reported, he said.
The Islamic Center of San Diego says it is the largest mosque in San Diego County.
"We have never experienced a tragedy like this before," Taha Hassan, Imam and Director of Islamic Center of San Diego, said of the center at a news conference.
Hassan said he's sending "prayers and standing in solidarity with all the families in our community here, and also the other mosques, and all the places of worship in our beautiful city."
"It is extremely outrageous to target a place of worship. Our Islamic center is a place of worship. People come to the Islamic center to pray, to celebrate, to learn, not only Muslims, but we have people from all walks of life," Hassan added.
"The religious intolerance and the hate, unfortunately, that exists in our nation is unprecedented," Hassan said.
"We strongly condemn this horrifying act of violence," Tazheen Nizam, the executive director of the San Diego chapter of the Council on American-Islamic Relations, said in a statement. "Our thoughts are with everyone impacted by this attack. No one should ever fear for their safety while attending prayers or studying at an elementary school."
San Diego Mayor Todd Gloria told ABC News that "we immediately have increased patrols around religious sites, both our Muslim, Jewish and other faith communities across the city. And I imagine we'll maintain that posture for some time."
"[I] believe that once the investigation is complete that that security guard will be credited with a tremendous saving of many, many lives, including many children, an absolute hero who sadly lost his life, but for whom we're all grateful," Gloria said.
"Hate has no home in San Diego. Islamophobia has no home in San Diego," the mayor said during a press conference.
